The transgene contains the human genomic FUS locus from a 225 kb BAC, RP11-388M20 (BACPAC resource centre, Childrens Hospital Oakland Research Institute) with loxP sites, and an mCherry reporter gene. The exon 15 mutation (c. 1574C-T) was inserted separately by site-directed mutagenesis. Lines 1 and 3 were generated. (J:82809)
